From: Olmesartan reduces oxidative stress in the brain of stroke-prone spontaneously hypertensive rats assessed by an in vivo ESR method

Figure 3

(a) The effect of olmesartan on urinary norepinephrine (NE) excretion. Urinary NE excretion over 24 h, used as a marker of sympathetic activity, was increased only in the hydralazine (Hyd)/hydrochlorothiazide (HCT) group. *P<0.05. (b) The effect of olmesartan on the in vivo electron spin resonance (ESR) signal decay rates. In vivo ESR signal decay rates were measured on the days before and after treatment in each rat. The signal decay rate was significantly decreased after treatment with olmesartan, whereas it was unchanged after treatment with Hyd/HCT or no-treatment. *P<0.05.
